Dyne Testing supplies a complete range of surface energy measurement equipment & systems for the determination of wetting characteristics of solid materials. For optimum adhesion when printing, gluing, painting or coating on various substrates it is necessary to have a high surface energy.
The strength of attraction between a material and a coating is determined by the relative surface energy/surface tension of the materials. The higher the solid’s surface energy relative to the liquid’s surface tension, the greater the molecular attraction, this draws the paint, ink or adhesive closer for high bond strength. The lower the solid’s surface energy relative to the liquid’s surface tension the weaker the attractive forces are and this will repel the coating.
Determining the surface energy can be easily achieved by measuring contact angle or by use of Surface Energy Test Pens or Inks (Dyne level testing). We supply a range of surface energy measurement equipment; Dyne Test Pens, Test Pen 38 Dyne, Dyne Test Inks, Drawdown Test Equipment, and Contact Angle Meters.
